.Application filed November 7, 1924. Serial No. 248,842.

T 0 all whom it may concern:

Be 1t knownv that. I, GEORGE O. Brno s'rnorr, a citizen of the United States,-res1ding at Neenah, county ofll innebago, and State of Wisconsin, havelnvented new and.

useful Improvementsin WVooden Flasks, of which; the following is a specification.

This inventionrelates toimprovemeuts in -Wooden .fiasks.

. quately secured .t ogether and have been very shorthved,.due..to rott ng .atpomts Where lsqtheavooden sides offtheflasks overlapped f produce a long lived wooden; flask, through the medium of fittings which will even outliveflthe side members of the flask and may be used with new side members to construct additional flasks after the originaldevice is no longer useful. It is the primary object so of this invention to provide anoreland improved type of flask having.thejabovementioned, adrantages.

In the drawings:

embodying this invention. I

Figure 2 is a side elevation of the flask shown in'Figure 1.

Figures 3 and 4 are detail views of fittings employed in the construction of a flask oi.

this character.

Like parts are identified by the same reference characters throughout the several views.

It will be noted that the side Walls of each part of the flask are made of Wood. The

' 'Wooden. flasks .as heretofore constructed have had the advantage of. light we ght -but. 1 have. usually. been/cheaply built, made- 1 Walls include side members 5 and 6, and end.

I inner and an-outer fitting. It will be ob vious that each pair of" fittings so secured embraces two contiguous sides, otflthe flask to retain them in their desired relative position. .Seats may conveniently be provided at 13 and 14: upon the inner and outer flasks respectively, to receive a, flush bearing con- .tacttrom the nuts 15 and .16 of boltlQ.

Where the flasks are subjected ,to considfable. pressure it. is desirable to .increaselthe strength .of the .conn ction between the pairs .ofclalnps andthe Wooden sides of thefiasks.

This. may conveniently be done by. .pro riding either .the;..inner ,or outer .clamps. or

botluwvith studs 20 which. are best. shown in Figure 3,..and which are indicated in" dotted lines in li igure 1. These studsare received in apertures provided for the purpose; inthe sides of the flasks and provide apositive connection which secures the sides, against separation. Thus, the inner. and .outer clamps not onlyexertaubii'iding' or clamping. action ,upon thesides but mayalso conveniently be connectedpositively with the sides. i

*It is particularly to be.notedsthatv the areas in the corners or the flasks are left unobstructed torthe' free. circulation of'air. There 1s no; overlapping ofthe'wooden -sides ofthefiask at the corners thereoflland .fact isv ofzgreat importance 'since I..;have found that. by'facihtatmp; and encouraging Figure 11s a plan vlewoita two-part flask air circulation across the exposed ends of the side members of'the flask the effect of rot becomes greatly decreased and; the side members .Wlll be comparatively long-lived. It is the ends ofsuch members, where the grain is exposed, that are particularly subject to rot, and-if thewliask is constructed in the manner heretofore common in the art, there is a constant accumulation of water at the ends of thentlasksides so that decay is continuous. at these points. .In the present device theair circulationWhichis af .forded, due to the construction of the side anembers and ofthe clamps, tends-to carry away any moisture from these polnts and to prevent any accumulation of moisture.

So far as the above description goes the cope and'the drag of the flask-areidentical in construction. Each ina be regarded as a complete article by itself. ,VVhere the two parts are used together. however, it is :easy to attach fittings to the exterior clamping members for ensuring the accurate seating of the'cope upon the drag. To this end bolt apertures are provided at 21 in the exterior clamping member 10, both of the cope and of the drag. Bolts passed through these apertures are used to secure to the clamping members 10 of the drag, upon one end thereof, the members 22 which include offset tapered studs 23. To the correspond ing end of the cope are fastened angles 24: having laterally projecting arms 25 which receive the tapered studs n3 attached to the drag. The curvature of the studs is such as to enable them, with arms 25, to permit the function of a hinge, whereby the cope and drag are detachably connected.

At the opposite ends of the cope and drag the bolts passed through apertures 21 may serve, in the case of the drag, to support a fitting having a laterally projecting arm 27 with a hemispherical boss 28, whereas the clamping member 10 attached to the cope has an arm 29 provided with a hemispherical recess adapted to receive the boss 28. These devices are self centering and ensure the accurate alignment of the cope and drag.

It is to be noted that the construction of the parts herein described is standardized both for the reason that the castings applied to the cope and drag as clamping devices are identical, and for the further reason that these castings are provided with apertures at such points as interchangeably to receive the several fittings 22, 24*, 27, and 29. Thus, the parts cannot only be eco nomically manufactured and assembled but they are accurate and serviceable and, due to the long life afforded to the wood sides by the provision of air circulation across the ends of the side members, the devices combine lightness in weight with great durability. The objects specified for the invention, therefore, are satisfied by the disclosure herein.

.I claim:
